I was a little bit disappointed by the talk. He didn't introduce theortical concepts of cryptography to show what are the differences between strong and weak cryptography (IND-CPA, IND-CCA).

Also I missed side notes on why SHA1/MD5 is broken and what are problems for hashcode. For me it was a lot about showing functions and extensions that one can look up in the manual, but not enough deeper stuff about cryptography and ciphers in general.

Just a good talk, informative overview with some hands on at the end.

I was positve suprised. Thx

Good presentation. Unlike some other talks this talk was tailored to PHP.

Great Presentation. Strong Code Examples.

one of the few talks that were actually tailored to PHP.
Talk didn't went very fluently, felt like you had to figure out what to tell next. Not sure what caused that.
